What is silicone antifoam for water-based ink?
Silicone Antifoam for water-based ink is a special foam control additive designed for water-based ink systems. It is compounded with modified silicone and dispersant. The product has stable chemical property and will not damage ink pigment dispersion.
It can handle foam issues in ink production and printing operation. It has fast defoaming and long-term foam inhibition performance. It will not react negatively with binders, pigments or other ink additives. It will not cause colour floating, pinholes or shrinkage marks on printed pattern. It is widely used in water-based ink production and printing workshops.

Main application scenarios of silicone antifoam for water-based ink
Silicone antifoam for water-based ink suits: water-based flexo ink, water-based gravure ink, paper printing ink, plastic film water-based ink, ink grinding stage, ink circulation during high-speed printing.
Two key working stages: ink grinding stage and high-speed printing stage.
During ink grinding stage, strong stirring introduces plenty of air and foam. Foam will reduce grinding efficiency and make pigment dispersion uneven. This antifoam quickly breaks foam in grinding tank, removes micro air bubbles and ensures uniform particle size of pigment.
In high-speed printing stage, ink circulation and roller shear continuously generate tiny foam. Micro bubbles will create pinholes, missing print and uneven ink layer on printed substrate. The antifoam suppresses new foam generation, keeps stable ink flow and guarantees clear, complete printing parns.
Key features of silicone antifoam for water-based ink
Easy to disperse into water-based ink system, no floating oil
Fast defoaming speed and durable foam suppression
Low addition amount, no impact on ink colour and tinting strength
No pinhole, shrinkage or recoating problems on printed surface
Good compatibility with water-based resin binders
Resist shear force under high-speed stirring and circulation
